Three questions for Sri Lanka, three questions for Bangladesh
A two-match series in Pallekele will present two uncertain teams a stiff examination of their Test-match mettle
To win in Sri Lanka, spinners generally need to take a lot of wickets. One of Sri Lanka's problems has been that since the retirement of Rangana Herath, their spin attack has fallen away somewhat. Where their spinners collectively averaged 27.80 at home in Herath's last three years, they average 32.62 since his exit.
Although since December Sri Lanka's batting has been sporadically impressive, such as in the first innings at Centurion or the second innings at North Sound, these successes have been interspersed with dramatic, harrowing collapses. In their last 12 Test innings, Sri Lanka have failed to make 200 on five occasions. Two of the worst nosedives came in their last series at home, against England, against modest bowling, when they were out for 135 and 126 - innings in which they surrendered the series. If they go into self-destruct mode again, they could cede another match.
Coach Mickey Arthur has been adamant that players raise their standards, and have ruled certain players out of contention purely on fitness grounds. And still, Sri Lanka's long history with muscle and soft-tissue injuries continues to plague them. In addition to being without Embuldeniya in this series, they are also missing seamer Kasun Rajitha, while rookie batter Pathum Nissanka has been struggling with a niggle as well (but is expected to be fit for the series). There are many theories on why injuries seem to plague Sri Lanka more than most other teams. Some find fault with the conditioning, others point to a lack of recent cricket, or to developmental issues going back to the players' formative years. Whatever the case, rare is the series from which Sri Lanka emerge with all their key players intact.
Bangladesh's Test record is such that it is considered inevitable they will not threaten on foreign soil. They have won only one away Test in the last five years, and since that one win, which came in Sri Lanka in 2017, they have lost each of their nine Tests on the road, all by heavy margins.
What would make it more difficult for Bangladesh in Sri Lanka this time is Shakib Al Hasan's absence. His stature as a Test allrounder makes him particularly difficult to replace. Mehidy Hasan Miraz performed admirably against West Indies recently but he has a lot to do to earn the allrounder's tag. This time the selectors have picked the 34-year old Shuvagata Hom as a batting allrounder when five years ago, during his last Test appearance, he was counted as a bowling allrounder. This is the sort of confusion that can arise when Shakib isn't around; no Shakib is always an advantage to the opposition.
Bangladesh's catching was one of the most worrying aspects of their disastrous New Zealand tour last month. They dropped ten catches in the ODIs and T20Is, which cost them results and momentum, and netted a bit of embarrassment as well. When the team returned from the tour, newcomer Nasum Ahmedoffered an explanation for the dropped catches that was the stuff of internet memes: "Their sky is very clear and their weather is nothing like ours."
